Abstract
Description
Technical Field
[0001] This utility model relates to the field of children's nasal cavity cleaning technology, and in particular to a children's nasal cavity cleaning device. Background Technology
[0002] When allergic reactions or pathogens trigger rhinitis or sinusitis, the nasal and sinus mucosa undergo significant changes due to the immune response. On the one hand, the mucosal tissue becomes congested and edematous, further narrowing the already narrow nasal passage. On the other hand, the mucosal cells secrete excessively, producing a large amount of viscous secretions, i.e., nasal mucus. These two pathological processes create a double obstruction effect, leading to a sharp reduction in nasal ventilation and resulting in difficulty breathing. To ensure smooth breathing and prevent pathogens from accumulating in the nasal cavity, it is necessary to clean out the viscous nasal mucus with a cleaning solution. Existing nasal cleaning devices use a squeezing elastic reservoir to inject cleaning solution into the nasal cavity, thereby flushing out the thick nasal mucus. However, the amount injected depends entirely on feel, and if not handled carefully, too much can be injected, leading to choking. Especially when children use these devices, parents usually assist in squeezing the elastic reservoir. Parents cannot effectively adjust the squeezing speed according to the water pressure in the child's nasal cavity, which can easily cause choking and lead to otitis media. Utility Model Content
[0003] The purpose of this invention is to provide a nasal irrigation device for children, thereby solving the aforementioned problems in the prior art.
[0004] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A nasal irrigation device for children includes a reservoir bottle, an infusion tube, an injection assembly, a first one-way valve, a second one-way valve, and an irrigation head. One end of the infusion tube is connected to the bottom of the reservoir bottle, and the other end is connected to the irrigation head. The injection assembly includes a transparent injection chamber and an injection piston. The injection piston is slidably disposed within the transparent injection chamber. The piston rod extends through the transparent injection chamber and into the outside of the chamber. The outer wall of the transparent injection chamber is marked with graduations. The end of the transparent injection chamber away from the piston rod is connected to the infusion tube. A first one-way valve and a second one-way valve are respectively disposed near the injection chamber in a section of the infusion tube between the reservoir bottle and the injection assembly and in a section between the injection assembly and the irrigation head. The flow direction of the first one-way valve is from the reservoir bottle to the injection assembly, and the flow direction of the second one-way valve is from the injection assembly to the irrigation head.
[0005] The beneficial effects of this utility model are as follows: When parents clean a child's nasal cavity, they first push the push rod to move the injection piston forward to the side wall where the transparent injection cavity connects to the infusion tube, thus expelling the air from the transparent injection cavity; then they pull the push rod to move the injection piston backward, and the cleaning solution in the storage bottle enters the transparent injection cavity through the infusion tube and the first one-way valve. After the cleaning solution in the transparent injection cavity reaches a certain amount, the cleaning head is slowly inserted into the child's nasal cavity. By referring to the scale on the outer wall of the transparent injection cavity, the push rod is pushed forward, and the injection piston moves forward, allowing the cleaning solution to pass through the second one-way valve and the infusion tube in sequence, and finally be discharged through the cleaning head, thus cleaning the nasal cavity. During the rinsing process, parents can control the pushing speed and amount of the push rod according to the size of the child's nasal cavity and the scale on the outer wall of the transparent injection chamber, thereby effectively controlling the water flow rate, water pressure and liquid volume of the cleaning head, and thus effectively avoiding choking.
[0006] Based on the above technical solution, the present invention can be further improved as follows.
[0007] Furthermore, a return spring is provided on the push rod. One end of the return spring is connected to the pressing end of the push rod, and the other end is connected to the outer wall corresponding to the transparent injection cavity.
[0008] Furthermore, a finger frame is provided on the side wall of the transparent injection cavity.
[0009] Furthermore, the cleaning head contains a sponge, and multiple liquid outlets are provided on the side wall of the cleaning head that contacts the sponge. Attached Figure Description

[0012] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.
[0013] Example 1 like Figure 1As shown, a pediatric nasal irrigation device includes a storage bottle 1, an infusion tube 2, an injection assembly 3, a first one-way valve 41, a second one-way valve 42, and an irrigation head 5. One end of the infusion tube 2 is connected to the bottom of the storage bottle 1, and the other end is connected to the irrigation head 5. The injection assembly 3 includes a transparent injection chamber 31 and an injection piston 32. The injection piston 32 is slidably disposed within the transparent injection chamber 31, and the push rod 321 of the injection piston 32 extends through the transparent injection chamber 31 and into the outside of the transparent injection chamber 31. The outer wall of the transparent injection chamber 31 is provided with a scale 33. The end of the transparent injection chamber 31 away from the push rod 321 is connected to the infusion tube 2. The section of the infusion tube 2 between the storage bottle 1 and the injection assembly 3 and the section between the injection assembly 3 and the cleaning head 5 are respectively provided with a first one-way valve 41 and a second one-way valve 42 near the injection chamber 31. The flow direction of the first one-way valve 41 is from the storage bottle 1 to the injection assembly 3, and the flow direction of the second one-way valve 42 is from the injection assembly 3 to the cleaning head 5.
[0014] When parents clean a child's nasal cavity, they first push the push rod 321, causing the injection piston 32 to move forward to the side wall where the transparent injection chamber 31 connects to the infusion tube 2, thus expelling air from the transparent injection chamber 31. Then, they pull the push rod 321, causing the injection piston 32 to move backward. The cleaning solution in the storage bottle 1 enters the transparent injection chamber 31 through the infusion tube 2 and the first one-way valve 41. Once the cleaning solution in the transparent injection chamber 31 reaches a certain amount, the cleaning head 5 is slowly inserted into the child's nasal cavity. By referring to the scale 33 on the outer wall of the transparent injection chamber 31, the push rod 321 is pushed forward, causing the injection piston 32 to move forward, allowing the cleaning solution to pass through the second one-way valve 42 and the infusion tube 2 in sequence, and finally be discharged through the cleaning head 5, thus cleaning the nasal cavity. During the rinsing process, parents can control the pushing speed and amount of the push rod 321 according to the size of the child's nasal cavity and the scale 33 on the outer wall of the transparent injection chamber 31, thereby effectively controlling the water output speed, water pressure and liquid output of the cleaning head 5, and thus effectively avoiding choking.
[0015] Example 2 This embodiment is a further improvement on embodiment 1, as detailed below: The push rod 321 is provided with a return spring 322. One end of the return spring 322 is connected to the pressing end of the push rod 321, and the other end is connected to the outer wall of the transparent injection cavity 31. When the liquid injection piston 32 is pushed to the designated scale by the reset spring 322, the liquid injection piston 32 can be reset by releasing the push rod 321. The cleaning fluid in the storage bottle 1 is automatically drawn to prepare for subsequent rinsing, simplifying the operation steps and improving the ease of use of the device.
[0016] A finger frame 34 is provided on the side wall of the transparent injection chamber 31; the finger frame 34 on the side wall of the transparent injection chamber 31 can better realize single-hand pressing operation and further improve the convenience of device operation.
[0017] Example 3 This embodiment is a further improvement on embodiment 1, as detailed below: The cleaning head 5 is equipped with a sponge, and the side wall of the cleaning head 5 that contacts the sponge is provided with multiple liquid outlets 51; A sponge is installed inside the cleaning head 5 to reduce the impact energy of the cleaning fluid at the outlet due to hydraulic pressure. This effectively reduces the impact of the cleaning fluid spraying out of the outlet 51 on the nasal mucosa of children, further improving the comfort of using the device and alleviating children's resistance.
[0018] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
